Schistosomiasis haematobia
A human disease caused by the infection of parasitic worms SCHISTOSOMA HAEMATOBIUM. It is endemic in AFRICA and parts of the MIDDLE EAST. Tissue damages most often occur in the URINARY TRACT, specifically the URINARY BLADDER.
Muscidae
Schistosoma haematobium
A species of trematode blood flukes of the family Schistosomatidae which occurs at different stages in development in veins of the pulmonary and hepatic system and finally the bladder lumen. This parasite causes urinary schistosomiasis.
Schistosomiasis
Infection with flukes (trematodes) of the genus SCHISTOSOMA. Three species produce the most frequent clinical diseases: SCHISTOSOMA HAEMATOBIUM (endemic in Africa and the Middle East), SCHISTOSOMA MANSONI (in Egypt, northern and southern Africa, some West Indies islands, northern 2/3 of South America), and SCHISTOSOMA JAPONICUM (in Japan, China, the Philippines, Celebes, Thailand, Laos). S. mansoni is often seen in Puerto Ricans living in the United States.
Schistosomiasis mansoni
Schistosomiasis caused by Schistosoma mansoni. It is endemic in Africa, the Middle East, South America, and the Caribbean and affects mainly the bowel, spleen, and liver.
Ectoparasitic Infestations
Diflubenzuron
Schistosomiasis japonica
Schistosomiasis caused by Schistosoma japonicum. It is endemic in the Far East and affects the bowel, liver, and spleen.
Schistosoma mansoni
A species of trematode blood flukes of the family Schistosomatidae. It is common in the Nile delta. The intermediate host is the planorbid snail. This parasite causes schistosomiasis mansoni and intestinal bilharziasis.
Schistosoma
A genus of trematode flukes belonging to the family Schistosomatidae. There are over a dozen species. These parasites are found in man and other mammals. Snails are the intermediate hosts.
Liver Diseases, Parasitic
Schistosoma japonicum
Anthelmintics
Agents destructive to parasitic worms. They are used therapeutically in the treatment of HELMINTHIASIS in man and animal.
Biomphalaria
A genus of planorbid freshwater snails, species of which are intermediate hosts of Schistosoma mansoni.
Oxamniquine
An anthelmintic with schistosomicidal activity against Schistosoma mansoni, but not against other Schistosoma spp. Oxamniquine causes worms to shift from the mesenteric veins to the liver where the male worms are retained; the female worms return to the mesentery, but can no longer release eggs. (From Martindale, The Extra Pharmacopoeia, 31st ed, p121)
Splenic Diseases
Antigens, Helminth
Snails
Molluscacides
Agents destructive to snails and other mollusks.
Bulinus
A genus of small freshwater snails of the order Pulmonata, found throughout Africa and the Middle East, where it is a vector of SCHISTOSOMA HAEMATOBIUM.
Disease Vectors
Neuroschistosomiasis
SCHISTOSOMIASIS of the brain, spinal cord, or meninges caused by infections with trematodes of the genus SCHISTOSOMA (primarily SCHISTOSOMA JAPONICUM; SCHISTOSOMA MANSONI; and SCHISTOSOMA HAEMATOBIUM in humans). S. japonicum infections of the nervous system may cause an acute meningoencephalitis or a chronic encephalopathy. S. mansoni and S. haematobium nervous system infections are associated with acute transverse myelitis involving the lower portions of the spinal cord. (From Joynt, Clinical Neurology, 1998, Ch27, pp61-2)
Endemic Diseases
The constant presence of diseases or infectious agents within a given geographic area or population group. It may also refer to the usual prevalence of a given disease with such area or group. It includes holoendemic and hyperendemic diseases. A holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). A hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. (Last, A Dictionary of Epidemiology, 3d ed, p53, 78, 80)
